LLOYD CYRENIUS, OF NEW YORK, N.

CAPSULE.

Application filed June so, 1921. Serial No. 481,684.

. To all whom it may concern:

Be it known that LLOYD W. CYRENIUS, a citizen of the United States,residing at New York, in the county of New York and State of New York,has invented new and useful Improvements inCapsules, of which thefollowing is a specification.

The present invention relates to improve-. ments in capsules orcontainers for medicaments and more particularly the invention referstocertain improvements in capsules or the like by which the capsuleissealed and the contents thereof hermetically enclosed to avoid thepossibility of contam- With the foregoing and other objects in view, theinvention will be more fully described hereinafter, and will be moreparticularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or correspondingparts throughout the several views,

Fig. 1 is a perspective view of an im-' proved capsule constructedaccording to the present invention;

Fig. 2 is a side viewthereof;

Fig. 3 is a longitudinal sectional view therethrough Fig. 4 is a planview of'a built up series of the capsule elements; and Fig. 5 is asimilar vlew showing a portion of the device broken away and one of the"cagsule bodies detached.

eferring more particularly to the drawings, in Figs. 1, 2 and 3, I haveillustrated.

a form of the invention in which a single compartment 1 is furnished forbut one dose of the medicament which is filled therein through the mouthof the gelatine body 2 before the cap 3 is put in place. The

gelatine body 2 is of a construction and form corresponding,substantially to one of the complemental parts of capsules as now con--.

structed, except that in most'instances the body 2 will be of a greaterlength in order to hold the desired dose. The end wall 4 is rounded orconstructed on a section of a sphere as is usual in capsules, the otherend being left open.

As capsules are at present constructed, a second gelatine body similarto the body 2 is used having an open mouth fitted within or about theopen mouth of said body12 and cooperating therewith to provide an innerchamber of sufiicient size to accommodate the dose.

tion, the cap piece 3 is of a relatively infcrior length as comparedwith the body 2' Unlike this customary construe and is formed with arounded or spherical closed end wall 5 adapted to be fitted within theopen mouth of the capsule body 2 and to have a tight frictional fittherein to effectively hold the capvpiece in place. The curvature of theend wall 5 will guide the cap piece into the mouth of the body anddesirably a slight extension, such as indicated in Fig. 3, will takeplace in the mouth of the body 2 to afford a better gripping action ofthe body on the cap piece.' The cap,

piece 3 is also preferably made of'gelatine and is hollow inside. Afterthe cap piece 3 is in place, the outer openend thereof is preferablysealed over by a gelatin layer 6 or other suitable material to preventthe entrance of foreign matter into the hollow interior of the cap piecewhich might make the appearance of the article unsanitary.

Furthermore a coating or annular 'oint 7 of gelatin or some othersealing su stance is placed about the mouth of the body 2 at the meetingpoint therewith of the cap piece 3. The function of this joint is tohermetically seal the capsule body and to avoid the entrance of foreignmaterials or harmful bacteria which would interfere with the sterilecondition of the medicament within, and to hold the parts together.

Referring more particularly to Figs. 4 and 5, a number of the bodies 2are shown fitted in series with the rounded ends 4 projecting into themouths of adjacent bodies substantially the same distance as the cappiece. Each of the bodies is sealed by a ring 7 of gelatin or the like.Sucha construction provides a series of compartments or containingchambers in which successive doses may be placed and all held in anintegral unitary. containing capsule. If desired, bodies may he slippeduponone another to greater or less extent in order that the coma singlearticle and cap pieces are dispensed with for all of the bodies exceptthe last in the series, thus economizing to a large extent in the matterof material .and making it possible to commercially put up medic-a5ments at lower cost. The gelatine bodies 2 are broken off from the leftside of the built up capsule, Fig.5 showing the first in the series tohave been removed. In like manner the remaining bodies are detachedfrom-time to time until the whole is consumed, the last dose forinstance being procured by the removal of the cap piece 3.

Of course the order may be reversed and the cap piece 3 initiallyremoved thus progressing from right to left as shown in Figs. 4 and 5,but this is not believed to be asdesirable an arrangement, as the openends of the bodies from which a dose has just been delivered are apt toform pockets for foreign matter and contamination and on the whole thesanitary purpose of the article will not be so well subserved. Theannular coating 7 may with advantage be asolution of celluloid as thismaterial is very effective in its adherence to gelatine .and will uniteand incorporate the parts very closely, and it moreover possessesadvantages in its resistance to climatic and atmospheric conditions andit is impervious to water, mois ture and most foreign substances.

It is obvious that various changes and modifications may be made in thedetails of construction and design of the above specifias my bodiesthroughout the series, and aclosure member for the last body of theseries.

2.- A package containing a plurality of gelatinous hollow bodies, eachclosed at one end and open at its other end and having an enlargeddiameter thereat extending for a portion of the length of the hollowbody, said hollow bodies being adapted to be interfitted with the closedend of one body in the open enlarged end of the adjacent body to closesaid bodies ,one with the other throughout the series, a hollowgelatinous plug having a closed end and fitting there- 'at in the openend of the last body of the series for closing the same, and a closurefor the open end of said plug.

3. A package containing a plurality of gelatinous hollow bodies closedat one end' and open at their other ends andenlarged thereat forinterfitting with the closed ends in the enlarged ends throughout theseries for closing the hollow bodies one with the other, a hollowgelatinous plug having a closed end fitting in the open end of the lasthollow body of the series, a closure for the open end of said plug, anda layer of sealing material arranged between the contacting surfaces ofsaid bodies, plug and closure for. sealing the interiors of the same.

In testimony that I claim the foregoing hereunder.
